Because it is desirable to protect the bared end 15a of the cable 15 from* the corrosive action from the fumes and acid of the battery, I preferably practically close the endY of the opening 14 nearest the terminal .with a Wall 16 Which may be provided With a substantially angular cut or slot 1'? the opposing surfaces 17a and 17b ofwhich are coincident with the'corresponding. surfaces 1a of the block 1' and the surface 11a of the -free end 11, the apex of said angle being at or about clamp 3.v By virtue of this construction the cut is almost closed, When the clamp 3 is tightly drawn'around the end cfa cable of average diameter.

The manner in which my improved. connecter is Yused should now be apparent. As assembled in Figs. `1-, 2 and 5, the bolt 6 is slipped through the'hole 12 of the clamp 3 and is threaded into the hole 9v until the head 7 contacts with the i". outer surface of theV free end 1l ofthe strap the bolt 6. Y l Y angular slot or out 1 7V in the Wall v15 and theend of thecable Will `be practically enclosed WithinV clamp 3. The bared end 15",1 of the cable 15fis inserted into the hole or recess 14 of the clampr 3.

`When the end of the cable bottoms on the wall 16 the head of the screw is turned to dravv'the diameter of .the hole 14 and turning the bolthead 'l-Yand with it the bolt 6 to draw the strap l10 so tightly around the end of the cable that the latter cannot be Withdrawn Without loosening This will substantially close the the opening or socket 14 and protectedffrom the corrosive fumes and liquids or" the battery;

' Because the opening 14 is substantially cylinv drical, the clamping-pressure and the attendant frictionbetween the cable and the connecter vwill be substantially evenly applied', and distributed end of the bolt6 and turning the said nut to draw the free end 4a. of the strap 4 snugly around the terminal.

Y clamped in thestrap clamp 2.

thereafter thebared end 15EL of the cable 15 may But the'device is equallyadapted for rst attachment to thebattery terminal by inserting the bolt Sinto the opposite end of the threaded hole 9.

Thus by first inserting the end of the bolt 6 into the hole 5fof the end @of the strap 4 and -then turning the screWin the threaded hole v9 until the headr'l lengages the outer surface of the end la if of the strap 4, the clamp 2 may be slipped over the end of theA battery terminal "and the bolt 6 turned by its head 7 until the terminal. is tightly Now at any time be inserted. into the socket opening '14 and the nut 8 may be ,threadedover the end of the bolt extending through-,the holel2, and turned to draw4` the straprlOtightly aroundthe cable end 15e.,

Thus it is that my improvedconnecter can be readily iixedly connected to either a battery terminal or to a cable by a single bolt by merely vslipping the` free end of the bolt through the opening in the free end of the appropriate clamp land threading it into the body portion and having been secured tothe selected conductor the other clamp may be thereafter closed around another conductor by tightening the nut threaded lover the same bolt, and Without loosening the connection rst made.

While my deviceris primarily designed to connect a cable lead to abattery terminal` in the more. or less standardized relationship, with the battery terminalV vertically disposed, and the cable vhorizontally disposed,it is now clear that the strap 4 of the: clamp 2 might be integrally connectedto the top of the body 1 or V,the clamp 3 might be integrally connected to the end of the body l so that 'theter'minal and cable Would be disposed in parallel instead of transverse direction 01' for Connellg any two'other electrical conductors. v v f Thus referring to Fig. 6, the terminal clamp 2bl a and the cable clamp 3b may be parallel and extend from the saine sideof the block 1b Which isy provided with a threaded opening 9b into which is threaded the bolt 6b from either direction depending upon Which clamp'is first; to besecurely clamped to an electric conductor. vAs in the other'modications the openings l5b of the clamp Zband the opening 12b of the clamp 3b are smooth -Y openings larger than the bolt and through which the bolt may freely slide. v Y v y l In the modification-shown inFig'. 7 the axes ofthe clamps 2c and. 3CV are also parallel, but the straps extend from opposite sides of the block 1c. The holes 5C and 12c like the corresponding'holes in the other modifications are oflarger diameter than the'bolt 6C andis -threaded hole 9C in the block 1. f f Y l I-Iaving thus described my invention, what I claim and Vdesire to protect by LetterslPat'ent Aof* the UnitedV States is:1 1 v1.
